Hi Team,
I'm getting the error below, but no idea how to solve it.
Error detail as below :
Unable to process template language expressions in action 'Append_to_string_variable' inputs at line '0' and column '0': 'The template language function 'formatDateTime' expects its first parameter to be of type string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#formatdatetime for usage details.'.
Hi @Marthini_06 ,
Yeah so your formatDateTime() expression is a date type and you need to convert to a string. Please wrap your existing formatDateTime expression in a string() such as string(formatDateTime(your_code)). This will convert that value to a string and you can keep going. Please mark as a solution if this help! Always glad to help! Tom
